Hey, thanks for my laugh of the day! you answer your own question- it's a V-10?! does that sound complicated? It is an Audi- does that sound reliable? lol oh, my

Sheesh, that answer wasnt helpful. Reading the reviews from owners indicates few have higher mileage at the time of their report. Common issues seem to all be expensive to repair, especially if you do not intend to do-it-yourself. For example, compressor for air suspension is $1200 even from 3rd party, electronics have some reported weaknesses, and the biggest cause for me to pause in the upgrade from my A8 is the FSI engine. Read about carbon build up on the intakes that results from no fuel being sprayed over the valves and you have to think twice about a used S8 with the V10. The job is likely to cost you $2000-3000 to have them cleaned. Also, the newer S8 uses a timing chain and not a belt. Maybe it's more reliable, but if it breaks the whole engine has to come out of the car. The older engines could have the bumper removed and done in a few hours... As a result, make sure you can afford to operate the car, not just purchase it.
